The part came out perfect with the exception of finishing pass leaving a mark behind where the lead-out was, probably from the workholding that it was still taking a cut on the overlap.
Cycle time can be dramatically reduced if I don’t probe each tool every tool change but I’m waiting on a touch probe to come in that’ll act as my 0 offset reference.
